L/R TPS question

[Scott Allen]

So I got a light that says service tpms system. The L/R tire pressure shows "--" I figured the sensor had gone bad so when I put new set of wheels on I had them check it and they said it was still good, and for good measure moved that sensor to the R/F to see if the issue followed. It did not. The L/R still shows "--" What other issues could I have going on here. It's not that big of a deal, it's just super annoying seeing that little yellow light

Get all the sensors tested. When one sensor goes bad it’s not always the one that shows - - A lot of times the RF hub that receives the signal gets confused which sensor is in what location when one has failed.

I'll get that done, I think most places offer that for free. Thanks
